Barbari bread (Persian: نان بربری‎, romanized: nân-e barbari) is a type of yeast leavened Iranian flatbread. It is one of the thickest flat breads and is commonly topped with sesame or black caraway seeds. A notable characteristic of the bread is its top skin that is similar to pretzels or lye roll's skin due Maillard reaction that occurs during baking as it is glazed with a mixture of baking soda, flour and water prior to baking. It is widely known as Persian flatbread in United States and Canada.
